Understanding the FPR Family: FPR1 and FPR2
The family of formyl peptide receptors typically includes FPR1, FPR2, and FPR3. Among these, FPR1, a G protein–coupled receptor, is widely recognized for its role in innate immune responses. It is primarily activated by Formylmethionine-containing oligopeptides, which act as signals for phagocytic cells.
On the other hand, Formyl peptide receptor 2 (also known as Formyl peptide receptor-like 1 or FPRL1) represents a more complex, promiscuous member of the family. It is important to note that FPR2 is a low affinity receptor for N-formyl peptides, yet it possesses a unique ability to bind a diverse array of ligands, including specialized pro-resolving mediators. This versatility is why Formyl peptide receptor 2, as an important target, is frequently discussed in research circles regarding the regulation of biological resolution processes.
